This robot moves between the two parallel white lines on a black surface.
The robot uses 2 CNY70 sensors in order to detect the white lines.
It has two 6 V geared DC motors, two wheels and a caster ball wheel.
The robot was powered by a 9 V alkaline battery.
PIC16F628A was used as microcontroller for the robot.
L293D motor driver was used for the driving of the DC motors.
Motors were driven by differential drive system.
